Quick TakeGazing into the dial of the Jazzmaster Open Heart Lady Auto is like having a secret window into a starry night where the constellations are made of gears and jewels. The deep blue aventurine sparkles with a life of its own, a tiny galaxy on your wrist. But the real magic is the peek-a-boo performance of the movement. It’s not just a static cutout; it's a dynamic glimpse into the soul of the machine—the tireless pulse of the balance wheel, the intricate dance of the escapement. This isn't a watch that simply sits there; it lives and breathes, powered by the H-10 caliber that promises a long weekend's worth of autonomy with its 80-hour power reserve. It feels both technically impressive, thanks to the anti-magnetic Nivachron components, and artistically inspired. Flipping it over reveals the rest of the show through the open case back, a private encore of snail and pearled patterns reserved just for you. It's a statement of sophisticated curiosity.

DescriptionThe timepiece's architecture is centered around a stainless steel case with a diameter of 36mm and a thickness of 10mm. Its lug-to-lug width is specified at 18mm, providing a structured profile on the wrist. A sapphire crystal, selected for its high resistance to scratching, is treated with an anti-reflection coating to ensure maximum legibility of the dial under various lighting conditions. The dial itself is composed of blue aventurine, providing a unique, glittering background for the timekeeping elements. Water resistance is rated to 5 bar, which is equivalent to a depth of 50 meters or 73 psi, making it suitable for everyday exposure to water but not for submersion activities.

At the core of the watch is the Hamilton Caliber H-10, an automatic three-hand movement visible through both the signature open-heart cutaway on the dial and a transparent open case back. This movement is engineered for longevity and performance, offering an extended power reserve of 80 hours. The inclusion of a Nivachron balance spring enhances its resistance to magnetic fields and temperature variations, thereby improving overall timekeeping stability. The watch is affixed with a blue calf leather strap, identified by reference H6000002271. This strap is equipped with an Easy Click system for tool-free changing, measures 18mm at the lugs, and tapers to a 16mm stainless steel pin buckle for a secure closure.
